libstdc++-v3 Does Not Compile

[Mohamed Ezz <ezz at peregrine dot com>]

Hello All,

I am working on a port of C++ code from Windows to Linux. The code
uses the STL and uses namespaces extensively. I am getting compilation
errors like:

In file included from ../../source/cpp/idd/hwstring.cpp:13:
../../source/cpp/idd/hwstring.h:19: `::string' undeclared (first use 
here)

I decided to download the sources for libstc++-v3 and gcc-2.95.2 and
recompile everything. I use the following commands for the
configuration:

../gcc-2.95.2/configure --prefix /usr --enable-haifa
--enable-version-specific-runtime-libs --enable-languages=c++,java
--enable-long_long --enable-namespaces --enable-shared

Notice the --enable-namespaces switch. The problem is I keep getting
the following compilation error when I `make bootstrap`

c++io.cc: In method `struct __c_streampos __basic_file::seekoff(long int, _Ios_S
eekdir, _Ios_Openmode = operator |((enum _Ios_Openmode)1, (enum _Ios_Openmode)2))':

I would appreciate any prompt help/hint on this.
